I've got a Stellantis vehicle (admittedly, a higher trim one) and my girlfriend has a Model Y. I absolutely HATE driving the Model Y. Tesla's UX is far, far worse. The main thing I interact with in my car is CarPlay. Simple things CarPlay does well (making and receiving calls, providing directions, voice to text, playing music/podcasts, etc.) Tesla fails at and that's most of what a car UX is for these days.

I will literally never get a car without CarPlay. But even excepting that, Tesla's UI mostly sucks.

The answer to shitty buttons isn't shove it all 3 layers deep in a touch screen menu, it's better buttons.
